Abstract (en)
[origin: EP2226802A2] An optical pickup device includes a first optical system (2) and a second optical system (3). The first optical system (2) and the second optical system (3) each include a mirror member (24, 36) that reflects light from a light source (21, 31) to change a direction of propagation of the light to a direction substantially perpendicular to the information storage surface of an optical disc. The first optical system (2) and the second optical system (3) are arranged such that a direction in which light from a first light source (21) enters a first mirror member (24) is substantially perpendicular to a direction in which light from a second light source (31) enters a second mirror member (36).
